To quote from PlayStationLifeStyle.net (linked above): "A Sony patent has hinted that they will release external processors to make the console even more powerful – without the need for a PS4.
The benefits of an upgrade to the PS3 are obvious – allowing for a more powerful machine, without having to pay so much for a new console. However, the “PS3 External Processor” has its drawbacks: it wouldn’t give consumers the same experience as a full new console, and would run the risk of both fragmenting and confusing the market.
The patent expressly states that several external processors may be used:
In accordance with an alternative embodiment, two processor elements may be cascaded by each employing its respective BIC in a coherent symmetric multiprocessor (SMP) interface (or BIF) configuration. The coherent SMP interface (BIF) of each processing element is coupled to one another to set up a coherent interface there between."
